Topology Optimization


Topology optimization is an analysis that reveals how materials should be placed in the design usable space to achieve the optimal structure. Given the design space, loading conditions, constraints, and constraints, it calculates the arrangement of materials that maximizes the desired performance index. The optimum shape is found for the product use environment and specifications assumed in the design space model.

Calculation of the optimal shape that maximizes performance under constraint

Here is a simple example of topology optimization.

The green area on the left is the design space. In this space, an instruction is given for the shape to be “the lightest shape with a load point displacement of less than a(mm)” with the both ends fixed, and the loading is applied to three places.  

The process calculated using Altair Engineering's HyperWorks is shown in the figure on the right. The placement of materials is optimized by varying the density of each part in the design space. Red is the portion determined to be necessary and blue is the portion determined to be unnecessary. In this case, by devising the constraints, a steel bridge-like shape was calculated from 59 iterations of the calculation.

This is an example of topology optimization from a steel model to a resin model to derive the optimal shape.

We support the design of high performance products in a short period of time and at low cost, through the use of CAE.
